🔬 Science Element

Algae are tiny plant-like organisms that live in water and use sunlight to grow. When algae multiply quickly, they can form an algal bloom that turns water green. Blooms often happen when extra nutrients enter the water. Too much algae can block sunlight and use up oxygen, making it hard for fish and other lake life to survive.
